Worked on enhancing API documentation for the SuperMap/iClient-JavaScript repository, focusing on the GetLayersLegendInfoParameters interface. The effort centered on clarifying the usage and behavior of parameters such as bbox, mapScale, and returnVisibleOnly within JSDoc, providing detailed guidance for various option combinations. By aligning and harmonizing parameter descriptions across the JavaScript API documentation, the work aimed to reduce developer confusion and streamline onboarding. The approach emphasized technical rigor in documentation and API design, improving clarity without altering code. These improvements supported faster integration for developers and reduced support overhead, demonstrating a thoughtful approach to documentation as a core engineering task.
